The pulmonary artery pulsatility index in patients with severe aortic stenosis undergoing valve replacement

open access: yesESC Heart Failure, Volume 12, Issue 5, Page 3483-3493, October 2025.
Abstract Background and aims The pulmonary artery pulsatility index (PAPi), that is, the pulmonary artery pulse pressure (PAPP) divided by the mean right atrial pressure (mRAP), is an increasingly used invasive index of right ventricular function. We sought to assess the prognostic impact of the PAPi in unselected patients with aortic stenosis (AS ...

Impact of regional anesthesia on left and right ventricular performance after off-pump coronary artery bypass grafting: randomized controlled study

open access: yesВестник анестезиологии и реаниматологии
Introduction. New anesthesia techniques require evidence of the safety of their implementation, however there is still the opinion about negative impact of regional anesthesia on heart performance and central hemodynamics.

Simultaneous determination of the stroke volume and the left ventricular residual fraction with the fiberoptic- and thermodilution method [PDF]

open access: yes, 2017
Simultaneous measurements of the concentration of dye by a fiberoptic catheter and of the temperature by a thermistor catheter were obtained in dogs. No significant difference for cardiac output and stroke volume was found.

Vector Flow Imaging Compared with Conventional Doppler Ultrasound and Thermodilution for Estimation of Blood Flow in the Ascending Aorta [PDF]

open access: yes, 2016
Transverse oscillation (TO) is a real-time ultrasound vector flow method implemented on a commercial scanner. The TO setup was examined on a flowrig with constant and pulsatile flow.

Accuracy of a Novel Approach to Measuring Arterial Thermodilution Cardiac Output During Intra-Aortic Counterpulsation [PDF]

open access: yes, 2018
Objective: To assess the agreement between a novel approach of arterial and the pulmonary artery bolus thermodilution for measuring cardiac output in critically ill patients during aortic counterpulsation. Methods: Eighteen male patients aged 37-80years,

Our own, non-invasive method of measuring the cardiac output (CO) and stroke volume (SV) in children aged 7–9 during physical exercise [PDF]

open access: yes, 2017
Introduction: Cardiac output (CO) determines the cardiovascular system’s function and undergoes fluctuations in various physiological and pathological states.

Stable coronary syndromes: pathophysiology, diagnostic advances and therapeutic need [PDF]

open access: yes, 2018
The diagnostic management of patients with angina pectoris typically centres on the detection of obstructive epicardial CAD, which aligns with evidence-based treatment options that include medical therapy and myocardial revascularisation.

Investigations concerning the application of the cross-correlation method in cardiac output measurements

open access: yesBioMedical Engineering OnLine, 2012
Background In spite of numerous non-invasive examinations the “gold clinical standard” of cardiac output measurements is the invasive pulmonary artery catheterization by means of the Swan-Ganz catheter and the application of the thermodilution method to ...

A protocol for resuscitation of severe burn patients guided by transpulmonary thermodilution and lactate levels: A 3-year prospective cohort study [PDF]

open access: yes, 2013
Introduction: The use of urinary output and vital signs to guide initial burn resuscitation may lead to suboptimal resuscitation. Invasive hemodynamic monitoring may result in over-resuscitation.
